New Miller sprayer light on its feet

Grain Central, October 9, 2017

THE LATEST Miller spraying technologies with a lighter footprint to suit row crop and medium size farming operations are now available.

A new, adjustable chassis design on the new Miller Nitro 7310 sprayer has resulted in a 5 per cent lighter machine compared with the Nitro 5240, allowing improved flotation and less compaction. It has also produced an industry high, 2-metre ground clearance, which will better allow late season spray applications.

The new Miller Nitro 7310 self-propelled sprayer, featuring a 4500-litre stainless steel tank (or 3800L tank with 700L of direct chemical injection capacity especially to suit row crop farmers) is set to hit Australian shores early next year and replace the Miller Nitro 5240 model.

Miller’s Australian distributor, McIntosh Distribution’s Jon Bent, said a complete new, adjustable chassis design had resulted in a 5 per cent lighter machine compared with the Nitro 5240, allowing improved flotation and less compaction.

Even weight distribution provides balance, with near equal load on each tyre to maximise power to the ground while minimising compaction.

Mr Bent said this would be particularly beneficial for cotton, corn, sorghum and sugar cane growers, as well as irrigated cropping paddocks, where multiple spraying applications can cause compaction concerns.

The new chassis has also produced an industry high, 2-metre ground clearance, which will better allow late season applications in these crops, as well as winter crops like canola.

Importantly, the Nitro 7310 uses the innovative drive train system that has been one of the key attractions of the popular new Miller 6000 series sprayers, providing maximum power and up to 30 per cent fuel savings compared with equivalent-sized machines.

The drive train was redesigned with a variable displacement hydrostatic drive system and planetary torque hubs, providing faster responses to speed changes through more efficient transfer of power to the ground, even at lower engine RPM.

The planetary system is electronically controlled and provides a long list of new features like full-time traction control, cruise control, anti-stall, integrated speed limiting and four driver-programmable speed settings.

Engine and hydraulic service checkpoints are easy to access from the walkway by the engine compartment on the new Miller Nitro 7310 sprayer.

The Miller Nitro 7310 is powered by a 6.7L, 310-horsepower Tier 2 engine and offers a 56 kilometre per hour road speed with four-wheel dynamic braking.

A variable speed, hydraulic-driven cooling fan runs only as fast as it needs to, saving horsepower and fuel while reducing noise.

Mr Bent said another major benefit with the latest model in Miller’s popular, front-mounted sprayer range was the availability of a full range of boom options, including a 48.5-metre Pommier RA Falcon boom and Miller’s unique Spray-Air boom.

The Spray-Air booms have been used for a range of applications in a wide variety of crops, including cereals, canola, pulses, corn, cotton and sorghum.

The Spray-Air system allows for more targeted chemical applications through air-assist and air-atomisation technology, forming one powerful spray nozzle system. Growers have fingertip control of the droplet size and speed of the air delivery for any spraying application. They can consistently atomise spray droplets in a range from 200-500 millimetres per minute per nozzle – spaced 25 centimetres apart.

Mr Bent said the ability to reduce water rates considerably with Spray-Air, which had also provided the best spraying results, could effectively double the size of the 4500L tank on the Nitro 7310, allowing growers to spend more time spraying and less time filling.

The new 7310 also includes a change in suspension geometry to Active Hydralink suspension, providing a smoother ride, and a new, ultra-quiet cab offering maximum comfort, control and convenience. Luxury cab options include a 12-volt cooler under the leather instructor seat, rear camera and auto on/off headlights.

Redesigned lift arms, the removal of some componentry and large wrap-around windows provide better visibility and monitoring systems have been improved. Operating functions including speed, RPM, pressures, temperatures and fuel level, as well as a spray info bar with light-up section display, showing which boom sections are operating, are mounted on the ceiling so not to disrupt operators’ line of sight.

A right hand console chassis monitor, mounted on an adjustable swing arm, allows operators to easily program and control multiple sprayer functions, which are instantly displayed on the monitoring screen.

With the significant chassis changes and new features through to small alterations right across the machine, it all adds up to a brand new Miller sprayer,’’ Mr Bent said.
